General: Sagebrush (Artemisia spp.) is a stout, dense, upright shrub with blue-gray leaves and 3-6 inch flower stalks that stand up above the foliage, even after the flowers are gone. The aromatic leaves are narrow and wedge-shaped with notches in the blunt tip, and usually densely hairy. Keeps leaves all winter. Individually, the flowers are small, but together they form several blue spikes of color above the plant during spring. There are about 300 species in the genus Artemisia, but fortunately, only 21-31 species, depending on how you count, occur in Nevada.
